Time-saving facilitation and tools for ASHRAE 90.1 Appendix G PRM (LEED Energy Modeling).

Add To Quote  


  • Navigators cover ASHRAE 90.1-2004, 2007, 2010 and 2013; for the Appendix G (Performance Rating Method) or ECB Method (Energy Cost Budget)
  • Aligned with other LEED Navigators (e.g. LEEDv4) for project management
  • Addresses minimum ventilation requirements for LEED, ASHRAE 62.1 and ASHRAE 170; and allows for increased ventilation with associated energy impacts
  • Streamlines and drastically speeds up the LEED Energy calculation and submission process
  • Automatic multi-language reports in a format suitable for GBCI submissions
  • Significantly reduced times to set up and create separate proposed and baseline models
  • Unique built-in QA functionality – design team collaboration and tracking
  • Automatic generation of baseline building, system autosizing and ability to run proposed and baseline load calculations and dynamic simulations using Parallel Simulation Manager

Technical Details

Regional Applications

  • USA & Canada – LEED Credits for:
    • Minimum & Increased Energy Performance
    • Minimum & Increased Ventilation (IAQ)
    • Renewable Energy Production
  • UK & Europe – LEED (USA) well known within the region while Italy has just implemented its own version
  • Middle East & Asia – LEED (USA) rating system very well known within the region, plus, both Estidama and The Masdar Approach reference and use ASHRAE 90.1
  • India– LEED – India rating system uses ASHRAE 90.1 methodology
  • Australia & NZ – ASHRAE 90.1 HVAC system prototypes important for the Industrial & Public Building and Healthcare Green Star protocols. GBCA moving towards JV3 performance based model using these standard ASHRAE systems

Save Time with Automation

  • Instantly create all baseline models from proposed design model
  • Optimal Start option for system operation allows automated determination of start-up time to reduce energy consumption
  • Performs automatic rotation check to determine if 1 baseline or 4 rotated baseline models will be required
  • Automatically assign baseline constructions according to climate zone
  • Automatically create and size proposed HVAC systems (Including ASHRAE 62.1 ventilation)
  • Import and edit ASHRAE baseline prototypes and other pre-defined systems
  • Import room and thermal zone template data
  • Automatically includes daylight simulation in proposed model and baseline models
  • Compare proposed and baseline buildings data input side-by-side prior to calculation
  • Automatically undertake simulations across all 5 buildings using Parallel Simulation Manager

Increased Accuracy

  • Manage and edit data for all 5 models from one central file reducing input duplication and error
  • More accurately model ASHRAE 90.1 & 62.1 baseline systems using templates
  • Gain feedback early on to maximize LEED Energy Credits
  • Use the built-in Quality Assurance to reduce errors and facilitate team collaboration
  • Model in detail complex building geometry, HVAC or Renewable Energy systems
  • HVAC Sizing reporting included for the building, plant, systems, zones and rooms.
  • Streamlined annual daylight simulation within the annual energy simulation in the same model
  • Step-by-step options to add notes for designers inputs, which allow for transparent communication within the model
  • Step-by-step help files included for improved guidance

Streamline the Process

  • Structure the modeling process in a concise manner using the integral innovative workflow
  • Cut down on unnecessary data input and modeling duplication
  • Automatically create reports which mirror the format required for submission (LEED EAc1)
  • Integrate with other IESVE tools to perform a wide range of analysis simulations and check performance against other LEED credits
  • Import model geometry using our unrivalled interoperability which covers SketchUp, Revit, gbXML, MS-Excel and DXF
